MECHANICAL SYSTEM CONTAINING RAPIDLY WEARING PART AND SUPPORT, AND BUCKET, CONTAINING AT LEAST ONE SUCH MECHANICAL SYSTEM

摘要

FIELD: construction; machine building.;SUBSTANCE: group of inventions relates to bucket of construction works production mechanism with quick-wearing part. Mechanical system comprises quick-wearing part and support, which are part of construction works production equipment. Support includes base, nose, which is extended from the base according to main axis between proximal end, located next to base, and distal end arranged opposite to base, and on each side of base is a fitting place to accommodate projection related to quick-wearing parts, as well as three closed sides. Nose comprises a set of cross-sections in planes perpendicular to main axis, which vary in proximal direction, limiting increasing or permanent cross section areas, in particular, without limiting any decreasing cross-section areas, excluding fitting place for arrangement of connection device in the nose. At that, fitting place is made in base as extension of nose with open side in distal direction. At that, said nose comprises first zone, which is located next to nose proximal end and contains at least six flat surfaces, arranged in pairs opposite to each other, limiting cross-sections of first type, and second zone, which is located next to nose distal end and contains at least six flat surfaces, arranged in pairs opposite to each other, determining cross-sections of second type boundaries. At that, every second zone flat surface is less inclined relative to main axis, than first zone flat surface, which is located in its extension in proximal direction.;EFFECT: improvement of mechanical system, having longer service life.;10 cl, 9 dwg
